Adjustable Versus Fixed Loop Devices For Femoral Fixation In Acl Reconstruction

Abstract

Suspensory devices are widely used in the management of anterior cruciate ligament (ACL) tear. They include fixed- and adjustable-loop devices. The aim of this study is to compare clinical and functional outcomes between the adjustable loop device (group I) and fixed-loop device (group II). Methodology: This was a prospective randomized study. Both groups were equivalent in demographic, preoperative, and intraoperative variables. Thirty patients underwent femoral side graft fixation with adjustable-loop and thirty with fixed-loop devices. Assessment of clinical outcome was done with Lysholm score, and knee stability tests (Lachman test, anterior drawer’s test and pivot shift test). Patient evaluation was performed preoperatively and 12 months after surgery. Result: No significant differences were observed between Group A (Adjustable Loop) and Group B (Fixed Loop) in terms of age, injury duration, preoperative MRI findings, postoperative knee function, or Lysholm scores (p>0.05). Both groups showed similar outcomes in knee stability and rehabilitation progress, with minor complications and no significant differences in the need for additional interventions. Conclusion:There were no significant differences in graft laxity or functional outcomes between fixed- and variable-loop devices after ACL reconstruction, though the variable-loop group reported higher patient-reported outcomes at six weeks, warranting further clinical research.
